* Different cells in the body have different antigens on their surface – so you can
make monoclonal antibodies that will bind to specific cells in the body.
* Cancer cells have antigens on their cell membrane that are not found on normal
body cells – they’re called tumour markers.
* In labs you can make monoclonal antibodies that will bind to these tumour
markers.
* An anti-cancer drug can be attached to these monoclonal antibodies. This might
be a radioactive substance, a toxic drug or a chemical which stops cancer cells
growing and dividing.
* The antibodies are given to a patient through a drip.
* The antibodies target specific cells (the cancer cells) because they only bind to
the tumour markers.
* The drug kills the cancer cells but doesn’t kill any normal body cells near the
tumour
